Abstract

The method involves processing actual GPS position data and static data carried in the vehicle, and/or data derived from driver-vehicle systems, to form a parameter which is used to control the operation of at least one device or system in the vehicle. The parameter is be used to control the gear-change program of a stepped or stepless automatic transmission of a passenger vehicle or agricultural vehicle. The data derived form driver-vehicle systems may include information about the driving conditions: town, country, motorway, flat, hills, stop, go, jam, bend etc.

Description

Die Erfindung bezieht sich auf Verfahren zur Steuerung von Aggregaten und/oder Systemen eines Kraftfahrzeugs unter Verarbeitung von Informationen zur Erfassung der Fahrumge­ bung, des Fahrzustandes, zur Positionsbestimmung oder der­ gleichen.The invention relates to control methods of units and / or systems of a motor vehicle under Processing of information to record the journey Exercise, the driving condition, for determining the position or the same.

In den zurückliegenden Jahren wurden viele Vorschläge gemacht, um dem Fahrer eines Kraftfahrzeugs das Fahren, insbesondere in besonderen Situationen oder Fahrumgebungen, zu erleichtern. Zu den Dingen, die sich der Fahrer wünscht, zählen neben einem sicheren, komfortablen Fahrzeug Assi­ stenz bei der Orientierung, zum Beispiel im Stadtverkehr, ferner Hinweise, die ihm Unannehmlichkeiten, zum Beispiel Zeitverluste durch Staus, bereiten sowie technische Unter­ stützung in kritischen Situationen, zum Beispiel bei Schnee und Eisglätte.Many suggestions have been made in recent years made to drive the driver of a motor vehicle, especially in special situations or driving environments, to facilitate. The things the driver wants, count in addition to a safe, comfortable vehicle Assi tendency in orientation, for example in city traffic, further notices that inconvenience him, for example Loss of time due to traffic jams, prepare and technical sub support in critical situations, for example in snow and ice smoothness.

Um dem Fahrer die gewünschte Assistenz zu geben, wur­ den spezielle Informations- und Kommunikationssysteme zur Fahrerunterstützung und zur Beeinflussung des Verkehrs ge­ schaffen.To give the driver the desired assistance, the special information and communication systems for Driver support and ge to influence traffic create.

Zu diesen Einrichtungen, die im weitesten Sinne viel­ fältige Informationen bereitstellen, zählen beispielsweise Nachrichtensysteme zur Verbreitung aktueller Verkehrsnach­ richten, Verkehrsleit- und Informationssysteme und Systeme, mit denen Einfluß auf die Fahrmanöver genommen werden. Hierzu zählen beispielsweise Steuersysteme mit adaptivem Charakter zur Steuerung eines Pkw-Automatikgetriebes. To these facilities, in the broadest sense a lot Providing comprehensive information is one example Message systems for the distribution of current traffic news straighten traffic control and information systems and systems, with which to influence the driving maneuvers. These include, for example, control systems with adaptive Character for controlling a car automatic transmission.  

Einen hohen Verbreitungsgrad haben Telekommunikations­ systeme gefunden. Hierzu gehört der Mobilfunk, das Radio (RDS), Infrastruktursysteme (bakengestützte Systeme, auch zur Gebührenerfassung). Diese Systeme erlauben die Verbreitung aktueller Daten.Telecommunications are widely used systems found. This includes mobile communications, the Radio (RDS), infrastructure systems (beacon-based systems, also for fee registration). These systems allow that Dissemination of current data.

Mit Massenspeichern, wie zum Beispiel CD′s mit zum Beispiel digitalisierten Straßenkarten, lassen sich stati­ sche Daten in praktisch unbegrenztem Umfang im Fahrzeug selbst mitführen.With mass storage devices, such as CD’s with for Example digitized street maps can be stati virtually unlimited data in the vehicle carry yourself.

Neben den aktuellen und statischen Daten ist es üb­ lich, vom Fahrer-Fahrzeug-System abgeleitete Daten zu gene­ rieren. Aus diesen Daten läßt sich eine Stellgröße, bei­ spielsweise zur Steuerung eines ABS, gewinnen.In addition to the current and static data, it is common to derive data derived from the driver-vehicle system rieren. A manipulated variable can be obtained from this data for example to control an ABS, win.

Zu den bereits im Markt eingeführten Systemen zählen beispielsweise die Routenführung und Reiseinformationen.Systems already on the market include for example route guidance and travel information.

Die Realisierung vieler Lösungen, die auf eine Automa­ tisierung des Straßenverkehrs abzielen, scheitern an deren Komplexität, mangelnder Beherrschbarkeit, hohen Kosten, Sicherheits- und Produkthaftpflicht-Überlegungen.The implementation of many solutions based on an Automa targeting road traffic fail because of it Complexity, lack of manageability, high costs, Security and Product Liability Considerations.

Die der Erfindung zugrunde liegende Aufgabe besteht darin, einzelne Aggregate oder Systeme eines Kraftfahrzeugs im Sinne einer Fahrer-Assistenz oder Teil-Automatisierung zu beeinflussen, um die Sicherheit, den Komfort, die Wirt­ schaftlichkeit und die Effizienz eines Fahrer-Fahrzeug-Sy­ stems zu steigern. Verwendet werden hierzu Informationen, die entweder bereits allgemein verfügbar oder im Rahmen der Erfindung bereitzustellen sind.The object underlying the invention is in individual aggregates or systems of a motor vehicle in terms of driver assistance or partial automation to influence the security, the comfort, the host Efficiency and efficiency of a driver-vehicle system to increase stems. Information is used for this, which are either already generally available or as part of the Invention are to be provided.

Diese Aufgabe wird mit einem, auch die kennzeichnenden Merkmale des Hauptanspruches aufweisenden, gattungsgemäßen Verfahren zur Steuerung von Aggregaten und/oder Systemen eines Kraftfahrzeugs gelöst.This task comes with one, including the distinctive Features of the main claim, generic  Process for controlling aggregates and / or systems solved a motor vehicle.

Vorteilhafte Varianten des erfindungsgemäßen Verfah­ rens sind den Unteransprüchen 2 bis 17 zu entnehmen.Advantageous variants of the method according to the invention rens can be found in subclaims 2 to 17.

Weitere, für die Erfindung wesentliche Merkmale sowie die hieraus resultierenden Vorteile sind der nachfolgenden Erläuterung eines erfindungsgemäßen Verfahrens sowie dessen möglichen Abwandlungen zu entnehmen.Other features essential to the invention as well the resulting advantages are as follows Explanation of a method according to the invention and its possible modifications.

Im Rahmen der Erfindung wird zwischen aktuellen Daten, statischen Daten und Daten, die von einem Fahrer-Fahrzeug- System abgeleitet werden, unterschieden. Zu den aktuellen Daten zählen beispielsweise Daten zur Positionsbestim­ mung (GPS). Diese Daten können unmittelbar dazu verwendet werden, die Schaltprogramme eines automatischen Getriebes den geographischen bzw. den länderspezifischen Gegebenhei­ ten anzupassen. Zu diesen Gegebenheiten zählen auch Maß­ nahmen des Gesetzgebers, wie z. B. Abgasvorschriften, Ge­ schwindigkeitsvorschriften usw.Within the scope of the invention, current data, static data and data from a driver vehicle System are differentiated. To the current For example, data includes data for position determination mung (GPS). This data can be used directly for this the shift programs of an automatic transmission the geographical or country-specific circumstances to adapt. These factors also include measure took the legislature, such as B. Emission regulations, Ge speed regulations etc.

Abhängig von der erkannten Position kann beispielsweise ein geeignetes Schaltprogramm für die Ebene (Norddeutschland), für die Bergfahrt (Alpenregion), für Ballungszentren oder andere Fahrumgebungen adaptiert bzw. aktiviert werden. Der beträchtliche Applikationsaufwand zur Berücksichtigung von länderspezifischen Varianten bei der Implementierung von Steuerungen für automatische Getriebe entfällt. In diesem Sinne kann beispielsweise ein System zur Positionsbestim­ mung als zusätzlicher Sensor aufgefaßt werden. Als zusätz­ liche Sensoren in diesem Sinne können beispielsweise auch andere Informationen aufgefaßt werden. Mit Informationen, die Aufschluß über eine aktuelle Wettersituation geben, können andere Aggregate eines Kraftfahrzeugs, wie bei­ spielsweise ein ABS oder auch eine Klimaanlage bzw. eine Heizung oder dergleichen, ein- oder ausgeschaltet, gesteu­ ert oder geregelt werden. Wenn beispielsweise die Informa­ tionen zur aktuellen Wetterlage ergeben, daß in der Region, in der sich das Kraftfahrzeug gerade befindet, mit besonde­ ren Gegebenheiten, zum Beispiel Schnee und Eisglätte, Nebel oder dergleichen, zu rechnen ist, kann beispielsweise die Arbeitsweise eines ABS beeinflußt werden.Depending on the recognized position, for example, a suitable switching program for the level (Northern Germany), for the ascent (Alpine region), for metropolitan areas or other driving environments are adapted or activated. Of the considerable application effort to take into account country-specific variants in the implementation of Controls for automatic transmissions are eliminated. In this A system for position determination can make sense, for example tion as an additional sensor. As an additional Liche sensors in this sense can also, for example other information can be understood. With information provide information about a current weather situation, can other units of a motor vehicle, such as for example an ABS or an air conditioning system or one  Heating or the like, on or off, control be regulated or regulated.
